This is nothing new except that it is offered as a short course. One would think it wouldn't be needed in this day and time but evidently it is.
Yes, all that was taught at home back in my day, with pretty hard parental consequences when we forgot...
Here are 10 etiquette rules that everyone should master:
Always greet people with a smile and a hello. If you're not sure what to say, a simple "Hello, how are you?" will suffice. When meeting someone for the first time, it is also important to introduce yourself and make eye contact while shaking hands.
These are basic manners that show gratitude and respect. Always say "please" when making a request and "thank you" when receiving help from others.
This includes using utensils properly, keeping your elbows off the table, and chewing with your mouth closed. Also, wait until everyone is served before starting to eat.
Avoid using foul language, especially in public places or around children. Use polite and respectful language at all times.
Don't stand too close to people, and always ask before touching someone. Be aware of your surroundings and respect people's privacy.
Dress appropriately for the occasion and location, taking into account the dress code and cultural norms. If you are unsure of the dress code, remember that is always better to be slightly over-dressed than under-dressed.
Take care of your personal hygiene, including bathing regularly, brushing your teeth, and wearing clean clothes.
Pay attention to what people are saying and show interest in their opinions. Avoid interrupting or dominating the conversation. Also, be respectful and considerate of other people's opinions.
Avoid using your phone or other electronic devices when in the presence of others, especially during a conversation or meeting.
Be clear and concise when communicating with others. Avoid using slang or jargon that may be unfamiliar to the other person. Be mindful of your non-verbal communication, such as body language, as it can convey a lot of information about your intentions and emotions
Most of the above came from the writings of Emily Post decades ago, with a bit of update for the 21st Century.
